Regex String Generator

Regex to Strings tool can automatically generate a list of string examples matching the expression based on input regular expressions. This tool helps developers quickly verify regex matching范围 and understand various string forms the expression may match.

Core Functions

This tool parses regular expression structure to generate all possible matching strings. Supports common regex syntax including:

• Character groups and character ranges
• Alternatives and grouping
• Quantifiers (such as ?, +, *, {n}, {n,m})
• Character classes (\d, \w, \s, etc.)
• Alternation operator (|)

Usage Instructions

1. Enter regex to test in input box
2. Use slider to adjust number of strings to generate (10-1000)
3. Click "Generate" button, tool automatically displays matching string list
4. Result panel shows actual number of strings generated and total number expression may match

Output Example

Input regex: /(((555) ?)|(555-))?d{3}-d{4}/

Generated matching strings may include:

• 555 123-4567
• 555-987-6543
• 234-5678
• 555890-1234

Result display format is "current displayed count/total possible matches", such as "10/500" indicates regex can match 500 different strings, currently displaying first 10.

Notes

• Ensure input regex syntax is correct, otherwise tool will display error message
• Some complex regexes may produce large number of matching results, recommend starting with smaller quantities to test
• This tool is mainly for understanding and verifying regex matching scope, generated strings are examples only
• For expressions containing infinite match possibilities (such as .* or \w+), tool generates limited representative examples
